T0 aZZ whom it may concern.-

Be it known that we, J OHN SHEARER, of the village of Preston, in thecounty of Waterloo, inthe Province of Ontario, finisher,and HENRYWILLIAM KAROH, of the village of Hespeler, in the county of Vaterloo, inthe Province of Ontario, Canada, machinist, haveinvented certain new anduseful Improvements in Double- Acting Rotary Gigs, of which thefollowing is a specification.

The object of the invention is to provide means by which the cloth mayberun with or against the cylinder without stopping the ma chine or makingany appreciable alteration in the gearing, and to so apply friction tothe feeding-rollers that the tension of the cloth being fed into themachine may be regulated; and it consists in the peculiar combinations.and the construction, arrangement, and adaptation of parts, all as morefully hereinafter described and claimed.

Figure l is a perspective view of the gig. Fig. 2 is a perspective viewfrom the opposite side. Fig. 3 is a sectional elevation of the machine.

In the drawings like letters of reference dicate corresponding parts. 7

In all gigs heretofore made there are none with which we are familiar inwhich the teaselcylinderis completelyinclosed, 'By our meth- 0d ofconstruction the cylinder is completely inclosed by the sides A, endsB,and lids O, as shown in Figs. 1 and 2, so that the operator may examinethe cloth, and at the same time be protected from any dust that mayarise by the action of the teasel-cylinder D upon the cloth.

E is a receptacle placed underneath the teasel-cylinder andextendingacross it, so as to receive the flocks falling from thecylinder D. F is another receptacle, made in the I form shown in Fig. 3,and designed to keep the cloth clear of the ground.

G is the main driving-shaft, on one end of which is situated thespur-pinion H and on the other the loose pulleys I and J and fast ordriving pulley K. One of these pulleys is driven by a straight belt andthe other by a cross-belt. When it is desired to drive the cylinder inone direction, the belt is moved from the pulley J to the driving-pulleyK.

I the feeding-roller.

Should it, however, be desired to drive it in the opposite direction,the cross-belt is moved from the loose pulley I to the driving-pulley K.As this system of pulleys and belts is common and well known, and as noclaim is made thereto, we have not shown the belts in the drawings.

The gear-pinionH meshes with the gear- Wheel I), which is situated onthe spindle M. On the same spindle is placed the bevel-pinion N, whichmeshes with the bevel-pinions O and U on the spindle 0. On the ends ofthis spindle are placed the bevel pinions Z and m.

n and p are bevel-pinions situated on the ends of the feeding ordelivery rollers a and b.

P is a pivoted lever'having a forked end, q,

arranged to fit into the recess in the collar r I on the spindle 0. Whenit is wished to make the roller (1 a feed-roller, the end q of the leverP is brought against the collar 1", so as to movethe spindle 0longitudinally and bring the bevel-pinions N and 0 into gear, and alsothe bevel-pinion m into gear with the bevel-pinion p, situated on thespindle of the feed-roller a. Should it, however, be desired to make theroller 1) the feed-roller, the lever P is moved so as to bring itsforked end q against the collar r, so as to move the shaftlongitudinally and bring the bevel-pinions N and U into gear, and alsobevel-pinion Z into gear with the bevelpinion n on the end of thefeed-roller b.

In Fig. 3 we show by dotted lines the course of the cloth as it passesthrough the machine.

For the purpose of illustration, we will suppose the roller (1, asrepresented in .Fig. 1, The cloth passes between the rollers b and d,over the roller 6, down to the roller f, whence it passes over therollers z, 71', and g, and then down to the roller f, up to the rollere, and then between'the rollers a and c, and out of the machine. Asshown in this figure, the points at which the teasels of the cylinder Doperateupon the cloth are be tween the rollers f and gandff and i. Asthe cloth is joined together at some suitable point.

there is a continual operation upon the cloth ICO of nap on the cloth,or in one direction and then in the other to give a different nap to thecloth.

For the purpose of regulating the extent of surface of cloth upon whichthe cylinder D is to act, we pivot on the frame A spur-pinions jarranged to mesh with the racks, 7:, upon the outer ends of which therollers i and g are pivoted. These spur-pinious j are operated by handfrom the outer side of the machine by sprocket-wheels :v and chains 2,operated by means of winches '20, as indicated in Fig. 2. In this figurewe also show on the ends of the spindles of the rollers a. and I)grooved pulleys Q, to which are applied the friction-straps B. Thesestraps are connected to thejaws of the pivoted levers S, which areadjusted on the quadrants T by the thumb-nuts i. \Vhen the cloth passesout of the machine between the rollers b and d, the thumb screw i may beadjusted so as to bring such a friction upon the pulley on the end ofthe roller a as to give the desired tension of the said roller upon thecloth passing into the machine.

It will be seen from this description that our machine may be easilyoperated, may be used as an up-and-down gig, and that by our sys tem ofbevel-gears the motion of the cloth may be changed without stopping themachine.

W'hat we claim as our invention is- 1. The combination, with theteasel-eylinder and its inclosing-frame, of the receptaeleE beneath saidcylinder, and the receptacle F for the purpose specified.

2. The combinatiomwith the main shaft and feeding-rollers, of a spindlearranged at right angles to said main shaft, bcvel-pinions O U on saidspindle intermediate of its ends, bevel pinion N, means for impartingmotion thereto from the main shaft, the pinions Z m n p, and means forshifting said spindle endwise, sub stantially as and for the purposespecified.

The combination, with the frame, shaft G, spur-pinion H, spur-wheel L,bevel-pinions N O U, and spindle 0, of the bevel-pin ions 1 m atopposite ends of said spindle, the rollers a b at opposite sides ofsaidframe, and the bevel-pinions p n on said rollers a I), respectively, andmeans for moving the said spindle endwise, substantially as described.

l. The combination, with the roller a and pulley Q thereon, ot' thequadrant T, lever S, thumb-nut t, and friction-strap R, passing oversaid pulley and connected to said lever, substantially as and for thepurpose specified.
